To 'all 'whom t may concern.'

Be it known that we, LYMAN C. JOsnPHs, Jr., a citizen of the United States, v`and Lnvnnnr'r H.`CUTTEN, a subject of the King of Great'Britain, residing in Allentown, in the State of Pennsylvania, have invented certain new and useful Improvements in Heating and Ventilating Means `fo: Motor- Propelled Cars,` ofwhichthe following is a specification, 'reference being had to the accompanying drawings, forming a part hereof.

The problemfof heating the bodies of cars propelled by internal combustion engines should find itssolution, it is believed, in the transference of heat from the propelling "motorlto the car. The diiiiculty offdelivering heat from the motor to the car elliciently and in useful form is recognized in the art and known attempts have not been satisfactory. The present-invention proposes to `f transfer heatfrom themotor to air which maybe constantly circulated and recirculatedfrom the heating mediuml through the carbo'dy. More particularly, 'the invention proposes that'the air tobe `hea-ted shall pass over -the radiator coils through which is constantly circulated vwater y'heated by the motor. Thissolution leadsto the real in- "v'e'ntive thought which resides in making *available Vthe conventional water cooling radiator of the motor `as avheating'medium I'for thejair and the"employment` of the con- 'ventional ra'diatorfan` as a' circulating'ela y1nent` 'forthe 'heating air. In practice, it has been found l' 'impracticable fto realize the ob- `jects-'of the'present invention in a construction where' the radiator is mounted in 'front of the ynrotorand so` the preferred embodi- "inent of the invention willfnd this' radiator mounted in rear "of the motor andin `communication. with `both the motor bonnet and lthe car-body.

"A further object vofthe .invention isfto provide a`-"heating system of the 'character 'fldescribed 'which shall serve Yequallyasa-n i effective Ventilatingsystem-for theca r `body in'both summer` and'w-iuiter'.v the action being such-'asfto insure, in'a controllable'manner, the constantrnovement of' air ofapredeten ymined temperature through the body Vof the carandthelinaintenance, within limits, of a predetermined temperature of the water Withinv the radiator coils,

In accordance with the invention-the'radirator and its fan may be placed in communication with the car 'body by means' of adjustable dampers and the car `body may be placed in communication with Ythe 4atmosphere through suitable dampers to the end that the current of warm air mayhave vcommingled therewith any desired volume of air at atmospheric temperature. Further, theradiator may have its coils placed in direct. communication with the atmosphere through adjustabledampers to permit the direct discharge of' heated air Vrather than its circulation through thecar body. By means ofthe dampers indicated any desired conditions affecting either the heating for ventilation of the car 'body in f either summer or winter'inay be obtained andthe cooling of the motor governed forgreatest efhciency.

Other features, of the system and incidental advantages will appearwith greaterxparticularity hereinafter irl-'connection with the detailed description of'the preferred'ernbodiment illustrated in .the` accompanying respectsto the character of the car inwhich "the system is incorporated though it 1s true thatthe most practicable embodiment thereofwill be found in a construction where the radiator is placed'atthe rear ofthe motor and communicates' with the -car body. As

yshown in the-drawings the-body a is mounted ion `-a Vchassis b which yis Vsupported by liangedtractionl wheels' b1 and avbogey truck What/ing flanged car wheels o3. VwTheinter- Ynal combustion engine k'which propelsithe car is mounted onthe chassis b at the 'front end ithereof, in accordance with usual practice and is housed within thevbonnet o. The radi- Vator'd lfor the-motor is disposed at the rear "thereof and ncludesthe--coils d1 and. thai-an (Z3 disposed within the coils. Extending rearwardly from the radiator is the cowl a). rllic type of fan Z2 employed is one which draws in the air centrally thereof and throws it out radially.

Broadly speaking, the invention contemplates thc transference of heat from the propelling motor to the car body by means of air heated by the motor. The heating of the air can be done most effectively by passing it over coils which radiate heat from warm water circulating therethrough and iirst heated by the motor. Such a heating medium might not be an element of the cooling system of the motor itself but in adapt-ing the invention to practical use it is proposed. to employ the conventional radiator d in accomplishing the desired heat transference. Further, it is proposed to employ the fan d2 of the radiator as a circulating element for the heated air which is to be passed constantly through the car body and over the heating coils (Z1. This fan :l: is, accordingly, normally in communication with the interior of the car body as through an opening e in a dash plate el and through an opening in a second dash plate f1, which last-named opening may be closed or opened to any desired extent by adjustable dampers g movable by the car-man. The air drawn in centrally of the fan (Z2 and thrown ont radially thereby across the tubes (Zlf is led by ducts i/ on opposite sides thereof lengthwise of the body from whence it is discharged into the body through one or more registers h2 controllable by danipers 7b3 So much of the system as has been described would provide for the constant circulation and recirculation of the heated air from the car body over the coils all, these coils being called on only to provide sufiicient heat to make up for 'the heat losses suffered by the air during its circulation. Heated air from the motor also passes constantly to the fan d2 and is likewise thrown out by it over the coils (Z1.

In weather which is not extreme it may be desirable to temper and freshen the heated air which is in constant circulation by ad.- mitting to it a stream of air directly from the atmosphere. A convenient means for effecting this cooling is shown conventionally a cowl shutter 'i controlling the admission of atmospheric air to the space between the dash plates el and fl. This shutter 1'. is un" der the control of the car-man and may he closed or opened to any desired extent. indicated by the arrows in Figures l and 4f the air passing' the shutter commingles with the air from the car body before the latter is picked up by the fan f/". In this condition of operation some of the warm air within the car body may escape,v therefrom through suitable ventilators provided therefor.

i exclusion of any hot air currents.

Vvthe tubes (Z1.

In the third condition to be taken care of it may be supposed that the weather is extremely mild, as in summer, and the cooling and ventilation of the car is desired to the in the improved system` the passage ofv heated air from the coils d1 into the car may be prevented by providing shutters h4 in the ducts it preferably opposite the coils (Z1 so that the air passing over the coils will escape freely into the atmosphere when the shutters 7b4' are opened. In such a case the heated air will not pass rearwardly through the longitudinal ducts It under the car body. However, the fan cl2 will act constantly to draw air from the car body so as to maintain a constant circulation of the air passing into the body through suitable ventilators. The

system, therefore, serves as an admirable cooling and Ventilating` arrangement for the body.

Ars described, it will be understood that the heat from the motor is madeavailable for the purpose of maintaining the air currents within the car body at a predetermined tempera-ture and replacing the heat losses thereof. The coils of a radiator for the motor placed at the rear thereof enable this heat transference to be conveniently and eiiiciently accomplished.

The fan for such a radiator further serves as a convenient blower for drawing air from the car body and forcing such air after additional heating, if desired, back to the car for recirculation. This same fan operating in a similar manner may serve as a ventilating element where it draws in additional cool air from the atmosphere or, in hot weather, expels air from within the car into the atmosphere in a steady stream. Taking into account the prevailing atmospheric temperatures and the temperature required within the car body, just so may the controlling temperatures be regulated to insure the maintenance of a predetermined temperature of the cooling water passing through This measure of control enables the operator to keep the engine working at the most eiiicient temperature.

Changes in details of design and a rearrangement of the parts which do not affect the principles underlying the successful practice of the invention may be made without departing therefrom providedthe results sought for are obtained by means which fall within the scope of the appended claims.
